Support/FAQs

Create a profile for each type of club. You can name the profiles by club like “8 iron” or “Driver”. Your MTRx will vary some depending on the club; your driver will have different acceleration and speed than an easy wedge shot.

This can be caused by your Portrait Orientation lock being on. When this is on, MTRx thinks your iPhone is top up even when you place it top down in your waistband. When the lock is on you will see a circle with a lock inside next to your battery indicator on the status bar. Other apps like your calculator will not shift to landscape mode either.

To turn the Portrait Orientation lock off, from the spring board screen, tap the Home button twice. Slide the row of apps at the bottom to the right until the Portrait Orientation icon appears. Tap it to unlock it.

Yes. Secure it in the same place and manner each time you record swings. Consistent placement and use will provide consistent results. We recommend putting the iPhone in your waistband just below your navel or a little toward your lead leg side. Do not place the iPhone on the side of your hip because your hip joint and muscles there can affect the sensors and skew the data.

The user guide is available in the app itself. The Getting Started information from the main screen covers your initial use of Golf MTRx. Many of the other screens have an info button, a white circle with the letter i, that reveals context sensitive help and user guide information.

There is also a What the Numbers Mean button on the Your MTRx, Chart, and Score screens that explain the numbers shown on each view.

More information about using, assessing, and learning with Golf MTRx is available on the website.

The Getting Started Quick Start steps show you how to record a swing. Once you are in recording mode, you can swing anytime whenever you are ready. There is no prompting or count down from the app.

For best results, the iPhone must be tightly secured to your hips. If the iPhone slips or slides, in any way during the swing, the data will not be accurate. We recommend buying a commercially available iPhone holder strap for your waist or an iPhone case made of rubber or any other tacky, non-slippery material for better grip in your waistband. Do not put the iPhone in a loose pocket.

Take your address position and hold still for one second before starting your swing. You can make a small forward press movement with your hips. Try to swing at a different time than someone else next to you on the driving range. MTRx listens for the impact sound and can be misled if there are a lot of external noises happening when you swing.

Practice swings where the club hits the grass or mat will record. Practice swings in the air will not record.

Are you taking practice swings or really hitting a ball? Practice swings in the air will not record. MTRx needs to hear an impact sound to record your swing.

Is the Microphone at the bottom of the iPhone or top of the iPod touch uncovered so it can detect impact?

Did you check out the Getting Started tutorial on the main screen?

Is your portrait orientation lock off?

How are you securing the iPhone to your waist? It should be inside your waistband or belt and tight enough so it won’t slip or slide around as you are swinging.

Did a phone call or other alert interrupt your recording? This will turn recording off.

There is a known problem in Golf MTRx with golfers who use a forward press of their hips to start their swing. This will be fixed in an update release soon. Try swinging without the forward press just to make sure swings are recording. Normally, a forward press should be OK as long as it is less than about 30 degrees of forward turn.

Golf MTRx honors your iPhone or iPod touch volume setting control for all apps. Press the Home button twice to access the volume control slider and make the adjustment you want. Ring volume does not affect sound volume from MTRx or your other apps. Make sure your iPhone is not silenced.

For best results, the iPhone must be tightly secured to your hips. If the iPhone slips or slides during the swing, the data accuracy may be affected. Tucking or placing the iPhone into the waistband of your pants, behind your belt will work fine. The iPhone or iPod touch can be in front or back. It can be offset to either side wherever it is most comfortable. The side of you hip is also fine.

Orientation of the iPhone does not matter. It can be portrait or landscape, facing toward or away from your body. Try to keep it top up or down, or on either side, parallel or perpendicular to the ground. Make sure that your Portrait Orientation Lock is off so MTRx can detect the orientation properly.

You can also use a holder that clips onto your belt. If you do, we recommend you clip it so the iPhone is inside your belt facing your hip. This will keep it firmly against your hip to ensure accurate data. Holders that strap around your waist work very well. These holders can be ordered from many online retailers. We also recommend using an iPhone case made of rubber or any other tacky, non-slippery material for better grip in your waistband.

Golf MTRx uses a patent pending swing recognition technology that is able to discern a real golf swing from other movements a golfer makes between swings. Golf MTRx does not prompt or tell you when to swing; you swing when you are comfortable and ready. Golf MTRx will record your swing and notify you via sound and vibration from your iPhone or iPod touch (touch does not vibrate). Simply hold your address position still for one second before you start your swing.

MTRx provides measureable data that is not available through video. MTRx provides the actual numbers for rotation, acceleration, deceleration, and speed while video is a visual representation of your swing. MTRx is intended to be a valuable source of additional information, not a replacement for video.

Phone calls and other messages will always be accepted. The app will run in the background during a phone call. The app does not detect motion while in the background, so you cannot record swings until the app is active and running in the foreground. If you were recording when you answered your call, just tap Start Recording again and start swinging!

Yes as long as the practice swing makes contact with grass or a mat such that there is a sound at impact. MTRx relies on sound to record a swing. Practice swing motions in the air with no sound will not be recorded. You can hit a soft foam or plastic whiffle type practice ball. These usually make enough impact sound for MTRx to record the swing.

MTRx uses one sensor to measure your pelvis motion. KVest has multiple sensors for your pelvis, upper body, and hands, and shows 3-D graphs of the kinematic sequence. MTRx shows the hips that form the base kinetic link of the kinetic chain. The accuracy of MTRx compares very favorably with KVest as the impact sensors in both sample at about 200 times per second (200hz).

Golf MTRx offers the Pro Tour averages for acceleration, deceleration, and peak speed, and uses those to calculate the Score. The app calculates ideal peak time to be 60% of the time from the start of your downswing until impact. The 60% ideal target comes from analysis of kinetic chain charts. Peak time is the point that your hips reach top speed and begin to decelerate.

Peak Time Is Important Because:

We need time for the torso and hands above the pelvis to fire before impact. If the pelvis reaches peak speed too close to impact, it’s a clear sign that the torso, arms, and club are not able to fire efficiently.

The pelvis will begin to decelerate when the upper body segments begin to engage and fire. The torso will apply pressure to the lower body and it has to be able to stabilize in time to support the energy from above.

There is no trick to decelerating as we all do it at some point. If you can accelerate, reach peak speed quickly, and begin decelerating sufficiently prior to impact, your torso and arms have time to catch up and bring the club to the ball efficiently with good power.

Decelerating at the right time before impact allows your pelvis to stabilize in time to transfer 1.5 times that much acceleration to your torso which can in turn transfer a multiple amount of speed to your arms, hands and club face at impact. This is the kinetic chain that when done efficiently, allows you to deliver the club face to the ball at maximum speed at impact.

As we have seen with PGA Tour players, there is not one specific swing that is the perfect swing. A good swing is based on your physical ability, experiences, knowledge and several other techniques, both physical and mental. The MTRx Score will guide you in the right direction as it will show the strengths and weaknesses in creating a stable base with your legs and pelvis. The more you use the app and work on adjusting your swing, the more you will learn what the proper MTRx are for you and what will make you a better player.

Whether you are a beginner or a scratch golfer, you will hit some shots better than others. When you hit a really great shot and record it, you can now see your MTRx of that swing. The swing MTRx can be saved as a Baseline or Favorite swing so you can refer to it later or compare it with your other swings now or in the future. When you save a Baseline or Favorite swing, you can tag it with a description, shot shape, club, and swing type.

These saved swings are important reference points for your MTRx that can change when you hit a high draw, a low fade, a duck hook, or a straight punch. You can only have one designated Baseline swing at a time, but many Favorites can be saved and used as Baselines. It is good practice to first save newly recorded swings as your Favorites so they will always be available. You can change your Baseline whenever you want by setting it from one of your Favorites.

How can I keep swings categorized by club? Create a profile for each type of club. You can name the profiles by club like “8 iron” or “Driver”. Your MTRx will vary some depending on the club; your driver will have different acceleration and speed than an easy wedge shot.

The app analyzes your data collected and compares it to Pro Tour averages in order to produce a MTRx score. The MTRx Score is a number between 0 and 100 that combines scores or four component data points: Acceleration, Peak Time, Deceleration, and Speed. The score and graphics help identify what deficiencies need to be addressed.

For one or more swings, the data points are compared to values a professional golfer would average for a full swing using a 5 iron or driver. The score is then calculated by combining the four values into an average and comparing your data with the tour pro data as percentages. Your MTRx with short irons or wedges may have lower speed and acceleration.

You can review it now and make adjustments based on the recommended drills or refer to the results later. Your recorded swings are saved until you clear all of them or delete some. You can also email results to your golf coach, compare results to past swings and receive feedback on how efficient your swing is against the tour average. One goal is to find what pelvis motion data works best for you and then work to repeat that more consistently. What the Numbers Mean buttons are available on the Your MTRx, Chart, and Score screens.

On your first tap, an alert will prompt you to select a MTRx Data Level based on your biomechanic knowledge. The Novice level is more about your score and shows less numeric data. The Expert level displays all the data.

Getting started is simple. Once you download the app with your iPhone, you simply launch the app, tap Getting Started, and follow the on screen instructions. Before you start swinging, you will need to ensure the iPhone is secured to your hips. For the best results, we recommend tightly securing the iPhone under your belt with the iPhone top down and the middle of the iPhone behind your belt. You can also use an iPhone holder belt strap that can be purchased online from various retailers.

Once the iPhone is secured to your hip, tap Start Recording and start hitting balls. If your volume is on, MTRx will “ping” when a swing is successfully recorded. To stop recording, remove the iPhone from your waistband and double tap the Stop button. The recorded swing list will chronologically display all the swings recorded. Tap on any of the swings to see animation, charts and recommended drills.

MTRx offers you a new form of feedback that is specific to each individual golfer without the distractions that may come with other teaching tools. Golf MTRx provides the ability for golfers to get biomechanic hip motion data at anytime, anywhere. Without spending thousands of dollars on sensor equipment, MTRx allows you capture the motion of your swing and create a digital representation of your results.

The MTRx data includes backswing, impact, and finish turn angles, tempo, rotational speed in degrees per second, acceleration, and deceleration. Once you have your swing captured, the software analyzes your data and tells you where you need to improve with recommended drills. This app allows golfers at all skill levels to have access to their own swing data and personalized drills that will help close a feedback loop between the golfer and instructor.

Yes, MTRx records both right and left handed swings. The swing recognition algorithm is nearly identical for both directions. The left or right handed options in your profile do not affect the actual recorded swing.
